Constructor Detail

AttributedString

public AttributedString(String text)
Constructs an AttributedString instance with the given text.

Parameters:
text - The text for this attributed string.

AttributedString

public AttributedString(String text,
                        Map<? extends AttributedCharacterIterator.Attribute,?> attributes)
Constructs an AttributedString instance with the given text and attributes.

Parameters:
text - The text for this attributed string.
attributes - The attributes that apply to the entire string.
Throws:
IllegalArgumentException - if the text has length 0 and the attributes parameter is not an empty Map (attributes cannot be applied to a 0-length range).

AttributedString

public AttributedString(AttributedCharacterIterator text)
Constructs an AttributedString instance with the given attributed text represented by AttributedCharacterIterator.

Parameters:
text - The text for this attributed string.

AttributedString

public AttributedString(AttributedCharacterIterator text,
                        int beginIndex,
                        int endIndex)
Constructs an AttributedString instance with the subrange of the given attributed text represented by AttributedCharacterIterator. If the given range produces an empty text, all attributes will be discarded. Note that any attributes wrapped by an Annotation object are discarded for a subrange of the original attribute range.

Parameters:
text - The text for this attributed string.
beginIndex - Index of the first character of the range.
endIndex - Index of the character following the last character of the range.
Throws:
IllegalArgumentException - if the subrange given by beginIndex and endIndex is out of the text range.

Annotation

AttributedString

public AttributedString(AttributedCharacterIterator text,
                        int beginIndex,
                        int endIndex,
                        AttributedCharacterIterator.Attribute[] attributes)
Constructs an AttributedString instance with the subrange of the given attributed text represented by AttributedCharacterIterator. Only attributes that match the given attributes will be incorporated into the instance. If the given range produces an empty text, all attributes will be discarded. Note that any attributes wrapped by an Annotation object are discarded for a subrange of the original attribute range.

Parameters:
text - The text for this attributed string.
beginIndex - Index of the first character of the range.
endIndex - Index of the character following the last character of the range.
attributes - Specifies attributes to be extracted from the text. If null is specified, all available attributes will be used.
Throws:
IllegalArgumentException - if the subrange given by beginIndex and endIndex is out of the text range.

Method Detail

addAttribute

public void addAttribute(AttributedCharacterIterator.Attribute attribute,
                         Object value)
Adds an attribute to the entire string.

Parameters:
attribute - the attribute key
value - the value of the attribute; may be null
Throws:
IllegalArgumentException - if the AttributedString has length 0 (attributes cannot be applied to a 0-length range).

addAttribute

public void addAttribute(AttributedCharacterIterator.Attribute attribute,
                         Object value,
                         int beginIndex,
                         int endIndex)
Adds an attribute to a subrange of the string.

Parameters:
attribute - the attribute key
value - The value of the attribute. May be null.
beginIndex - Index of the first character of the range.
endIndex - Index of the character following the last character of the range.
Throws:
IllegalArgumentException - if beginIndex is less then 0, endIndex is greater than the length of the string, or beginIndex and endIndex together don't define a non-empty subrange of the string.

addAttributes

public void addAttributes(Map<? extends AttributedCharacterIterator.Attribute,?> attributes,
                          int beginIndex,
                          int endIndex)
Adds a set of attributes to a subrange of the string.

Parameters:
attributes - The attributes to be added to the string.
beginIndex - Index of the first character of the range.
endIndex - Index of the character following the last character of the range.
Throws:
IllegalArgumentException - if beginIndex is less then 0, endIndex is greater than the length of the string, or beginIndex and endIndex together don't define a non-empty subrange of the string and the attributes parameter is not an empty Map.

getIterator

public AttributedCharacterIterator getIterator()
Creates an AttributedCharacterIterator instance that provides access to the entire contents of this string.

Returns:
An iterator providing access to the text and its attributes.

getIterator

public AttributedCharacterIterator getIterator(AttributedCharacterIterator.Attribute[] attributes)
Creates an AttributedCharacterIterator instance that provides access to selected contents of this string. Information about attributes not listed in attributes that the implementor may have need not be made accessible through the iterator. If the list is null, all available attribute information should be made accessible.

Parameters:
attributes - a list of attributes that the client is interested in
Returns:
an iterator providing access to the text and its attributes

getIterator

public AttributedCharacterIterator getIterator(AttributedCharacterIterator.Attribute[] attributes,
                                               int beginIndex,
                                               int endIndex)
Creates an AttributedCharacterIterator instance that provides access to selected contents of this string. Information about attributes not listed in attributes that the implementor may have need not be made accessible through the iterator. If the list is null, all available attribute information should be made accessible.

Parameters:
attributes - a list of attributes that the client is interested in
beginIndex - the index of the first character
endIndex - the index of the character following the last character
Returns:
an iterator providing access to the text and its attributes
Throws:
IllegalArgumentException - if beginIndex is less then 0, endIndex is greater than the length of the string, or beginIndex is greater than endIndex.
